Image to Base64

What is Image to Base64 Conversion?

Base64 encoding is a method of converting binary data, such as images, into a text-based format using 64 printable ASCII characters. When applied to images, this produces a data URI string that can be embedded directly into HTML src attributes, CSS background-url properties, or JSON payloads without requiring a separate file or HTTP request. The resulting string is approximately 33 percent larger than the original binary file, but the trade-off can be worthwhile for small images, icons, and sprites where eliminating extra network requests improves page load performance.
